ABSTRACT:
An electromagnetic pump characterized in that two independent coils disposed adjacent each other and via a common magnetic path are used for actuating a plunger and a valve, respectively, thereby preventing the generation of noises and abrasion during the operation of the pump. This also attains the quick return of the valve to its home position at the time when the pump stops, thus resulting in the complete stoppage of oil leak.
